Daniel Bonner, the global executive creative director at Razorfish, will oversee the London agency’s creative department when Chambers leaves at the end of March until a replacement is found.
Chambers joined Razorfish in a permanent position in 2012 after freelancing as a creative director.
Chris Mellish, the chief executive at Razorfish, said: "We always knew we wouldn’t have Sean for long. He is a true entrepreneur and someone who thrives on challenge. He leaves behind a reinvigorated creative department – one that has doubled in size during his two-year tenure."
At the same time, Razorfish has promoted its co-managing partners in London, Rob Fenton and Rob Watt, to European roles.
Fenton, who becomes the retail director for Europe, will work on accounts including Argos and McDonald’s.
Watt has been promoted to media director and will be charged with defining the strategy for and structure of Razorfish’s media practice, which counts Michelin as a client.
